Unity Layer (L2)

The Unity-Layer constitutes TPA Layer 2. While we acknowledge the existence of multiple Layer 2 solutions that align with TPA criteria, our current exclusive endorsement is for Optimism. The node implementation of Optimism has been forked with minimal essential alterations. In most instances, the Unity-Layer is envisioned to function as a Permissioned Layer 2.

Fraud Proof on Permissioned Layer 2

While decentralized fraud-proof on Optimistic rollups typically entails a 7-day duration, we anticipate that this challenge period can be significantly reduced when operating on a permissioned Layer 2. The reason lies in the fact that any fraudulent activity within a permissioned Layer 2 could pose a reputation risk for the entity overseeing the verse. Event occurrences remain verifiable as transaction data from Layer 2 is consistently mirrored on Layer 1 to ensure data availability.

Unity Builder

To become a Unity Builder, individuals must deposit a minimum of 1000 TPA into the staking contract. Within the Unity-Layer, a Unity Builder assumes responsibility for node operations and is obligated to maintain server functionality. Additionally, Unity Builders have the capability to configure which smart contracts can be deployed and which transactions can be executed without necessitating gas usage.

Free Gas For Users

On TPA Unity, users are exempt from bearing gas fees, as these fees are covered by Unity operators. The platform sustains itself by collecting transaction fees from Unity builders, thereby ensuring its long-term viability.
